For one week only, the groundbreaking music festival and concert tour Lilith is offering a great 2-for-1 offer on tickets at venues nationwide. This tour features top female musicians such as Sarah McLachlan, Kelly Clarkson, Mary J. Blige and Norah Jones all on one stage. Seeing them perform separately would probably cost you hundreds of dollars! With the 2-for-1 offer, the per-ticket price is as low as $10. Another added bonus: This month, Live Nation has eliminated service fees on tickets bought in June -- saving as much as $10 per ticket. Find out more information on this deal here. The sale ends on Tuesday, June 22 -- but the best seats will likely sell out long before that.
